CGR-30P Overview

Replace your Tachometer with EI’s CGR-30P, and bring glass panel technology to your panel today, without breaking the bank. The CGR-30P is a TSO’d, STC’d Primary Replacement engine instrument. What can it replace? The answer: most of the aircraft’s primary engine functions.

The beauty of the CGR-30P is that YOU get to choose many of the functions the CGR-30P replaces. Designed as a Cluster Gauge Replacement (CGR), the CGR will replace your Tachometer, Manifold Pressure, Fuel Flow Totalizer, EGT/CHT Bar Graph Analyzer, and more!

The CGR is divided into three separate screens. The three screens are the Main Screen, Secondary Screen, and the Fuel Management Screen.

Included: RPM (Arc Gauge), EGT/CHT Bar Graph, Fuel Remaining, Fuel Used, GPS/ Fuel Flow Data, Eng Time and Tach Time
Pick Second Arc: M.P. of Fuel Flow
Pick four primary functions with this Premium CGR-30P from this list: : Oil Pressure, Oil Temperature, Fuel Pressure (Turbocharged engine requires an upper deck transducer), Right Fuel Level (sensors not included), Left Fuel Level (sensors not included), Aux Fuel Level (Sensors not included), TIT, Vacuum, Volts or Carbon Monoxide Detector.

Choose up to five additional functions for the CRG-30p from this list and write it below: OAT, HP (requires RPM and MP), Flight Timer, Local time, Zulu time, Hydraulic Press (additional $250.00), Fuel Flow if not selected as primary (additional $295.00), G-Meter (additional $295.00), Fuel Level (s) for a tank that doesn't feed the engine (additional $98.00), Carb Temp or IAT (additional $95.00), Amps ($39.00) or Second Amp measurement (additional $195.00).

Option to add a smart charger below, adds two ports to charge that are USB compatible including smart phones, tablets, etc and also three ports for data downloading.

For faster processing, print the CGR-30P Premium Markings form out and complete it. Scan it into your computer and upload it during the check out process or email it to sales@emapa.aero.

CGR-30P Screens Overview

The Main Screen

The Main Screen displays the Tachometer and Manifold Pressure in large, beautiful analog arcs at the top of the instrument. Directly below the analog arcs, the respective digital values of each function are displayed. The analog display provides pilots with immediacy and quick reference values, while the digital display gives pilots the precision to accurately monitor their engine.

For aircraft without a constant speed prop, pilots may choose to display fuel flow instead of Manifold Pressure on one of the two arcs at the top of the instrument, which will free up another location on the Main Screen for another function.

In addition to the two arcs at the top of the Main Screen, the CGR also provides pilots with a complete, Primary Replacement EGT/CHT Bar Graph Analyzer. Each cylinder is monitored by the CGR, and if any engine temperature rises above or below programmed limits, the CGR will let you know immediately. The EGT/CHT Bar Graph Analyzer also has a Lean-of-Peak Mode and a Rich-of-Peak Mode for easy engine leaning. The CGR will let you know as each cylinder peaks, at what temperature each cylinder peaks, and how far below each cylinder is operating once they have peaked.

To the Right of the EGT/CHT Bar Graph Analyzer, the CGR contains three STC'd, Primary Replacement engine instruments. Choose between myriad options, including Fuel Pressure, Oil Pressure, Oil Temperature, TIT, Volts, Fuel Level(s), Vacuum, and more.

Bar Graph



The CGR-30P comes standard with a state-of-the-art, full-color bar graph which assists with ROP/LOP leaning. Additionally, the bar graph has both normalized and digital readout screens. No other bar graph in the industry comes close to providing the number of options the CGR-30P offers.

ROP Mode

The Rich-of-Peak mode on the CGR-30P informs the pilot when the first cylinder peaks, as well as how many degrees below peak the engine is operating.

LOP Mode

For Lean-of-Peak Operations, the CGR-30P informs the pilot as each cylinder peaks, at what temp each peaks, and how far from peak each is. For quick reference, every cylinder's peak information is constantly displayed and tattletale bars are shown above each cylinder, indicating where each cylinder peaked the last time the engine was leaned.

Normalized Mode

The Bar Graph can easily be Normalized, creating a baseline from which to monitor in- flight engine temperature changes. When Normalized, all of the bars start off at the same height. If any cylinder's column is not the same height as the others, than that cylinder's Exhaust Gas Temperature has changed in relation to the other cylinders. These changes can be critical indicators to problems occurring within your engine.

5 of 5 Saving fuel April 16, 2015
Reviewer: Anonymous Person  
I just wanted to let you know how my first cross country went with the new unit. My CHG and EGT were well within acceptable ranges. The surprising part was the amount of fuel I saved on the trip. Just being able to see the gph. As well as the hp% mixed with the CHT-EGT temp. And the leaning technique. I was able to save about 11 gallons of fuel on a 34 hour cross country. In Texas that’s almost 70 bucks right there. First trip out. Still learning and will still perfect it. But WOW.
